AI Technical Summary

Benefits of technology

[0011]An object of the present invention is to provide an image display that displays a high quality image and is hard to tamper with information thereon.

Problems solved by technology

Such a passport, however, may be tampered by replacing the photographic printing with another one.

When these techniques are applied to a passport, it is difficult to tamper with the passport.

However, the facial image recorded using fluorescent material cannot be perceived unless a special light source such as an ultraviolet lamp is used.

Although the facial image formed with pearl pigments can be perceived with unaided eyes, the particle sizes of pearl pigments are large, and therefore, it is difficult to form a high-resolution image using this.
